How to calculate the amount of sandblasting and rust removal of pipe brushes_faq

How to calculate the amount of sandblasting and rust removal of the pipe brush: (1) The metal structure is calculated according to the quality, with '100kg' as the unit. (2) The pipeline is divided into sub-items according to the inner and outer walls, and the pipe brush is considered as the unit of '10㎡'. (3) The equipment is divided into diameters, divided into sub-items according to the inner wall and outer wall, and calculated in units of '10㎡'. (4) The gas tank is divided into quartz sand blasting and river sand blasting, which are divided into sub-items according to the sink wall, sink bottom, middle cover plate, and metal structure. Except for the metal structure, the quality is calculated in units of '100kg'. The rest are calculated in units of '10㎡' by area. Chemical rust removal of pipeline brushes: chemical rust removal, also known as pickling rust removal. The metal surface is divided into two types: general and special, which are calculated in units of 10 square meters. The surface of the steel bars should be clean. Oil stains, paint stains, floating skin that can peel off when hit with a hammer, rust, etc. should be removed before use. Before welding, the rust on the solder joints should be removed. The rust removal of steel bars can generally be carried out by the following two methods: one is to remove rust in the process of cold drawing or straightening of the steel wire, which is more economical and labor-saving for removing rust from a large number of steel bars; the other is to remove rust by mechanical methods, such as electric The rust machine removes rust, and it is more convenient to remove the rust locally of the steel bar. In addition to this, manual wire brushes for rust removal, sand discs, sandblasting and pickling can also be used to remove rust. Welcome to www.mxbrushmachinery.com
